Backing up Unraid to a Synology NAS Drive

[aquariuz23]

Hello all. I have a Synology NAS that I use to backup my personal PC and still have some empty space in it that I would like to use as an external backup for the critical components in my Unraid server. While the array itself is "protected", I don't have any backups to anything else outside of the array, such as my cache, docker cache, and VM drives. These drives are nvme m.2 drives and while I trust them to be very reliable, I noticed that a few of them have already have a high count of reads and writes on them. Well, high as in the 20s-30s thousand writes; probably not that high, but again, I don't want to risk having a quick way to restore them if they ever decide to keel over. 

 

What would be the best way for me to back up these pool devices to my Synology NAS? They're in the same network so hopefully it's not too complicated. It could be something automated once every week or even once a month, since I rarely install new apps or update them. I have a Home Assistant VM that is probably the most active thing on my Unraid, so that's also critical. 

 

Any suggestions is appreciated. Thank you. Oh, and if I need to upload my diagnostic file, please let me know.

I backup all my things to a share except media files of the array. Then i backup that share to another unraid server with luckybackup. Since luckybackup is based on rsync i guess you could do the same to backup to synology.

I also use luckybackup to backup certains media files.

For the first backup ( to a share) i use several apps depending on the data to be saved:

- appdatabackup for docker appdata and flash backup

- home assistant samba backup

- borg backup included in nextcloud aio

- and soon a backup of a remote proxmox server synced with proxmox backup server

 

I found easier to centralize all backups to a share and then rsync that share to another server.

For vm i use easybackup. I wait for unraid 7 to reevaluate that point.
